-r lptport:LPT3:=/dev/printers/0 maps local drive and not printer

Hello,

I would like to print to a local printer from a DOS application that  
runs on our 2003R2 terminal server. I passed the parameter

-r lptport:LPT3:=/dev/printers/0

to rdekstop.
In the cmdline on the TS net use now shows me

     L:    \\TSCLIENT\LPT3

Why does it connect the printer to the drive L ?
Is this the L of LPT3 ?

Thanks
Andreas
